Trigger input
The trigger input is opto-isolated. The opto-isolator isolated voltages up to
50V.
Signal Function
TRIGI – Trigger input –
TRIGI + Trigger input +
The trigger input circuit is shown below:
The trigger input circuit operates as follows:
Logic 1 (on)
When a voltage of 5V to 24V is applied across TRGI negative ( – ) and TRGI positive (+),
the trigger input is logic 1 (on).
Logic 0 (off)
When a voltage of 0V to 2V is applied across TRGI negative ( – ) and TRGI positive (+),
the trigger input is logic 0 (off).
By default, the trigger is activated on a rising edge. However, this is configurable.
The trigger input sinks from 3mA to 10mA for voltages between 5V and
24V.
